2. Description of the Prior Art
In general, eyeglasses are used for compensating for poor eyesight or preventing a wearer's eyes from being dazzled by strong light beams. According to their utility, eyeglasses may be classified into various types of eyeglasses, including conventional eyeglasses, sunglasses, etc.
Worldwide, more attention is paid to health and people engaging in sports are increasing. Especially, people often ride bicycles or motorcycles and engages in activities at some risk in order to enjoy speed. In this case, riders of such vehicles put on various protective gear such as helmets for protecting heads, protective eyewear for protecting eyes, arm protectors, kneels protectors, gloves, etc. Above all, the protective eyewear is required to have a capability of preventing sunlight, wind or alien material from coming into eyes of a rider of a high-speed vehicle such as a bicycle or a motorcycle, thereby protecting the eyes of the rider.
Korean Utility Model registration No. 20-0246380 discloses a pair of multi-purpose eyeglasses having an inner frame which is detachably assembled with a main frame (outer frame) and prevents wind or various alien materials from coming into the inside of the eyeglasses, thereby providing convenience for the wearer.
As shown inFIG. 1, the disclosed eyeglasses include anouter frame5, aninner frame15, and asponge pad13. Theouter frame5 includeslens holding rims2 for holding lenses3, abridge1 formed between thelens holding rims2, and side protuberances4 formed integrally with outer edge portions of thelens holding rims2. Thebridge1 has agroove1aformed on a rear surface of thebridge1. Theinner frame15 has acentral protuberance12aformed on a front surface of abridge12 of theinner frame15 and clampingmouths11 formed at edge portions of a rear surface of theinner frame15. When theouter frame5 and theinner frame15 are assembled with each other, the side protuberances4 are inserted in the clampingmouths11 and thecentral protuberance12ais inserted in thegroove1a. Thesponge pad13 is attached to the rear surface of theinner frame15.
When a user uses the disclosed multi-purpose eyeglasses for conventional purposes, a user puts on only theouter frame5 holding lenses3. In contrast, the user puts on the assembly of theouter frame5, theinner frame15 and thesponge pad13 in order to prevent alien materials from coming into the wearer's eyes when playing high-speed sports such as bicycling or motorcycling.
In order to assemble the disclosed multi-purpose eyeglasses, a user must simultaneously insert thecentral protuberance12aof theinner frame15 into thegroove1aof theouter frame5 and the side protuberances4 of theouter frame5 into theclamping mouths11 of theinner frame15. In this case, it is difficult and inconvenient to insert thecentral protuberance12ain thegroove1abecause their positions need to be exactly confirmed in advance in order to engage them with each other.
Further, in order to disassemble theinner frame15 from theouter frame5, a user must hold theouter frame5 by one hand and theinner frame15 by the other hand, and then must pull them apart from each other. In this case, it is not easy to separately hold each of theouter frame5 and theinner frame15 assembled with each other by hands. This inconvenience is extremely cumbersome especially for individuals having large hands.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a pair of multi-purpose eyeglasses including an outer frame and an inner frame which can be easily assembled with and disassembled from each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 2 is an exploded perspective view of a pair of multi-purpose eyeglasses according to an embodiment of the present invention. As shown, a pair ofmulti-purpose eyeglasses100 according to the present invention includes anouter frame110 for holding lenses (not shown), aninner frame120 detachably assembled with an inside of theouter frame110, and asealing member130 attached to an inside of theinner frame120.
Theouter frame110 includes alens holder112 for holding lenses and a pair oftemple arms115 hingedly assembled with opposite side edges of thelens holder112. Thetemple arms115 extend backward from and can pivot around the opposite side edges of thelens holder112.
Further,side assembling ribs117 protrude inward from the side edges of thelens holder112 of theouter frame110 in parallel to thelens holder112, respectively. Each of theside assembling ribs117 has aside assembling groove117cor117dformed between theside assembling rib117 and thelens holder112. Each of the side assembling ribs may have either theside assembling groove117dhaving a slant surface and narrowing in the inward direction of the assembling groove as shown inFIG. 4 or theside assembling groove117chaving a stepped portion as shown inFIG. 5.
Theside assembling ribs117 have vertical lengths identical to vertical lengths of the side edges of thelens holder112, respectively. Of course, as shown inFIG. 6, theside assembling ribs117′ may have vertical lengths shorter than the vertical lengths of the side edges of thelens holder112, respectively. Also, it is preferred that opposite side edges of theinner frame120 which are engaged with theside assembling rib117 or117′ have shapes corresponding to theside assembling groove117cor117dof theside assembling rib117 or117′. That is, each of the opposite side edges of theinner frame120 to be engaged with theside assembling groove117dof theside assembling rib117 or117′ having a slant surface preferably has aninclined surface127aas shown inFIGS. 2 and 4, and each of the opposite side edges of theinner frame120 to be engaged with theside assembling groove117chaving a stepped portion surface preferably has astepped portion127cas shown inFIG. 5.
Further, afirst bridge114 located at a central portion of thelens holder112 has a central assemblinggroove114ahorizontally extending on an inner surface (rear surface) of thefirst bridge114. It is preferred that the central assemblinggroove114ahas a shape corresponding to a central assemblingrib124aformed at a front surface of asecond bridge124 of theinner frame120, so that the central assemblingrib124acan be seated in the central assemblinggroove114a. The central assemblingrib124amay have a size slightly smaller than that of the central assemblinggroove114a, so that external air can be introduced into the gap between the lenses and the face through the gap between the central assemblinggroove114aand the central assemblingrib124awhen theouter frame110 and theinner frame120 have been assembled with each other.
Meanwhile, thelens holder112 may have a plurality ofcentral pores116 and a plurality of side pores118. Thecentral pores116 and the side pores118 allows the external air to be introduced through them into the gap between theouter frame110 and theinner frame120 including the gap between thecentral assembling groove114aand thecentral assembling rib124a. It is preferred that thecentral pores116 and the side pores118 are formed both sides of each lens so that the external air can be smoothly introduced into the interior space defined by the lenses (not shown). Specifically, thecentral pores116 are formed through a pair of nose supports119 protruding backward from central portions of thelens holder112 and the side pores118 are formed through opposite edge portions of thelens holder112 outside of the lenses.
Theinner frame120 is detachably assembled inside of theouter frame110 having the construction described above. Therefore, a user can wear either only theouter frame110 or the assembledouter frame110 andinner frame120 according to necessity.
The outer surface (front surface) of theinner frame120 must have the same curvature as that of the inner surface (rear surface) of thelens holder112 of theouter frame110. Further, each of the opposite edges of theinner frame120 has theinclined surface127aso that theinclined surface127acan be in surface contact with theside assembling groove117dof theside assembling rib117 when theouter frame110 and theinner frame120 have been assembled with each other. Also, as shown inFIG. 5, each of the opposite edges of theinner frame120 may have the steppedportion127cso that the steppedportion127ccan be in surface contact with theside assembling groove117cof theside assembling rib117 when theouter frame110 and theinner frame120 have been assembled with each other.
Further, eachside assembling rib117 has astopper117bextending in a transverse direction from the surface of the side assembling groove. When theouter frame110 and theinner frame120 are assembled with each other,lower corners127bof theinner frame120 are placed on thestoppers117b, facilitating location of theinner frame120. That is, when thelower corner127bof theinner frame120 comes into contact with thestopper117bafter sliding downward along aguide surface117aof theside assembling rib117, thestopper117bprevents thelower corner127bfrom sliding downward anymore even when the user presses theinner frame120 downward.
Theguide surface117aof theside assembling rib117 extends from the top of theside assembling rib117 to theside assembling groove117cor117din gradual inclination, thereby enabling the opposite edges of theinner frame120 to be easily assembled with or disassembled from theside assembling rib117.
Further, thecentral assembling rib124aprotrudes from the front surface of thesecond bridge124 of theinner frame120 and extends in the horizontal direction. Thecentral assembling rib124ais formed at a position corresponding to thecentral assembling groove114aof theouter frame110. It is preferred that thecentral assembling rib124ahas a curved surface, so that theinner frame120 can be easily guided to its destined position even when theinner frame120 is assembled with theouter frame110 in any direction. For example, when theinner frame120 is either slid downward or elastically pressed inward of theouter frame110 with a snap, thecentral assembling rib124ais guided by and located in thecentral assembling groove114a, so that theinner frame120 can be easily in place inside of theouter frame110. Especially, when theinner frame120 is assembled with theouter frame110 by being slid downward, the gradually inclined central assemblingrib124acan be easily seated in thecentral assembling groove114a, so that theinner frame120 can be easily and conveniently assembled with theouter frame110.
As shown inFIG. 3, the sealingmember130 is attached to an inner surface of theinner frame120. The sealingmember130 has opposite ends137awhich do not cover theinclined surfaces127aof theinner frame120. Of course, in the case of theinner frame120 shown inFIG. 5, the opposite ends137aof the sealingmember130 do not the steppedportion127cof theinner frame120. Therefore, the sealingmember130 does not interfere with theside assembling rib117 when theinner frame120 is inserted in or drawn out of theside assembling rib117 of theouter frame110.
The sealingmember130 is made of porous sponge having a high elasticity and includes asponge portion132 attached to an inner surface of theinner frame120 and aleather portion134 attached to a surface of thesponge portion132. Theleather portion134 is in contact with a user's skin when the user puts on the multi-purpose glasses. In order to enable theleather portion134 to be in close contact with a user's skin when the user puts on the multi-purpose glasses, it is preferred that the sealingmember130 is subjected to a separate heat treatment so as to have a shape memory capability. The sealingmember130 having a shape memory capability prevents distortion of its surface when the sealingmember130 is attached to theinner frame120, thereby enabling the user to feel pleasant when the user has put on the eyeglasses.
Especially, theleather portion134 is a portion which comes into direct contact with the user's face when the user puts on the eyeglasses. Theleather portion134 is intended for preventing abrasion of thesponge portion132 and enhancing contact between the eyeglasses and the user's face. Further theleather portion134 prevents waste materials produced on the user's face, such as sweat, sebum, etc., from coming into thesponge portion132 made of porous sponge.
When themulti-purpose eyeglasses100 having the above-mentioned construction according to the present invention is assembled, side edges of theinner frame120 are inserted in theside assembling grooves117cor117dof theside assembling ribs117 of theouter frame110 from above and are then slid downward along the guide surfaces117aof theside assembling ribs117 of theside assembling ribs117. When thelower corners127bcomes into contact with thestoppers117bof theside assembling ribs117, theouter frame110 and theinner frame120 are completely assembled with each other. Then, thecentral assembling groove114ais seated in thecentral assembling rib124a, so that thefirst bridge114 of theouter frame110 and thesecond bridge124 of theinner frame120 are aligned with each other.
When themulti-purpose eyeglasses100 assembled as described above is disassembled, theinner frame120 is pushed upward, so that the side edges of theinner frame120 are slid upward along the guide surfaces117aof theside assembling ribs117. When the side edges of theinner frame120 have escaped out of theside assembling grooves117cor theside assembling grooves117d, theouter frame110 and theinner frame120 are completely separated from each other. In this case of theside assembling rib117 having theguide surface117a, the upper portion of theside assembling groove117cor117dis wider than the lower portion of theside assembling groove117cor117d, so that theinner frame120 can be separated out of the upper portion with clearance in theside assembling groove117cor117d.
As shown inFIG. 2, when theside assembling rib117 has a relatively long side wall, theouter frame110 and theinner frame120 can be assembled with each other with an enhanced power but can be separated from each other only after sliding a longer distance. In contrast, when theside assembling rib117′ has a relatively short side wall as shown inFIG. 6, theouter frame110 and theinner frame120 can be more easily assembled with or disassembled from each other after sliding a reduced distance. Therefore, each of theside assembling ribs117 or theside assembling ribs117′ may have various lengths according to necessities. In other words, the side wall of eachside assembling rib117 may have a length as short as possible on condition that the side wall should enable theouter frame110 and theinner frame120 to be assembled with or disassembled from each other.
Also, according to the present invention, theinner frame120 to which the sealingmember130 has been attached can be assembled with theouter frame110 by pressing them together with a snap by the fingers. In this case, theouter frame110 and theinner frame120 are instantly deformed by elasticity when theinclined surfaces127aof the side edges of theinner frame120 are inserted in theside assembling ribs117 or117′.
In order to separate theouter frame110 and theinner frame120 from each other, the side edges of thelens holder112 and thetemple arms115 may be held by the hands and are then widened. Then, thecurved lens holder112 is flexibly bent outward and theside assembling ribs117 become away from each other, and theinclined surfaces127aof theinner frame120 are then disengaged from theside assembling ribs117 and escape from theside assembling grooves117cor117d. Then, theinner frame120 is completely separated from theouter frame110. Thereafter, the side edges of thelens holder112 and thetemple arms115 are released from the hands, so that theouter frame110 restores its original shape by its elasticity.
In the multi-purpose eyeglasses according to the present invention as described above, theinner frame120 to which the sealingmember130 is attached can be easily assembled with or disassembled from theouter frame110 by sliding theinner frame120 into theside assembling grooves117cor117dof theside assembling ribs117 or117′. Further, the inner space inside of the lenses can be ventilated with external air through thecentral pores116, the side pores118, and thecentral assembling groove114a.
As described above, the present invention enables typical glasses for eyesight compensation or sunglasses to be easily assembled with or disassembled from each other. In other words, the present invention provides a pair of multi-purpose eyeglasses which can be used on various purposes.
Further, in the multi-purpose eyeglasses according to the present invention as described above, the inner frame can be easily assembled with or disassembled from the outer frame by sliding the inner frame into the side assembling grooves of the side assembling ribs. Especially, the guide surface formed inside of the side assembling rib facilitates sliding the opposite edges of the inner frame, thereby enabling the inner frame to be easily assembled with or disassembled from the side assembling rib. Also, the upper portion of the side assembling groove wider than the lower portion thereof enables the inner frame to easily escape from the side assembling rib.
Moreover, the central assembling rib formed at the inner frame is guided by and located in the central assembling groove, so that the inner frame can be easily in place inside of the outer frame.
Furthermore, a user can easily assemble or disassemble a pair of multi-purpose eyeglasses according to the present invention by means of the elasticity of the outer frame and the inner frame. That is, the user can assemble the inner frame and the outer frame with each other by snapping them on each other and can disassemble the inner frame and the outer frame from each other by simply widening the outer frame. The widened outer frame restores its original shape by its elasticity when the force applied to the outer frame is released.
Although preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
